SPECIFICATION forming part of Letters Patent No. 352,909, dated Application filed April 9, 1886. Serial No. 198,319. (No model.)

November 23,1886.

T0 (1. whom it may concern.-

Be it known that I,WILLIA1\I BILLINGS, a citizen of the United States, residing at Dover, in the county of Bureau and State 01' Illinois, have invented certain new and useful Improvements in Apparatus for Bending Metallic Strips; and ldo declare the following to be afull, clear, and exact description of theinventioinsuch as will enable others skilled in the art to which it appertniis to make and use the same, reference being had to the accompanying. drawings, and tothe letters and figures of reference marked thereon,which t'ornia partof this specitic-ation.

The invention will first be described in connection with the drawings, and then pointed out in theelaims.

Figure 1 ot' the drawings is a plan view of my invention; Fig. 2, a side elevation thereof, and Fig. 3 a perspective view of the article made. Figs. 4. and 5 are detail views of two i'orniers which I use.

in the drawings, A represents a spool, on which the strip of sheet metal is wound in many lengths of rail. This is formed of the longitudinal bars a, the crossbar-s rt, and the plate a. Through the crossbars a, and atl their junction, passes the spindle B, which has a noirronnd collar, I), preferably with four tapering sides. The spindle B has the disk I) on one end, parallel thereto a collar, b, and between the two the journal 12 The object of the disk is to conveniently receive the pressure of the wire spring 0, and being itself fast on the spindle, the latter is held while the desired length of strip for a rail is kept'taut to be punched and cut ofl. This spindle is taken from its open bearings, and one of the spools A full of the rail metal is passed upon it, so that the collar 1) enters a correspondinglyshaped hole in the plate a which is made fast by dowels to the cross-bars a, the latter being rigidly connected with the bars a. Thus it will be seen that the spindle when rotated must carry the spool. The spindle being placed in the bearings, a wire spring, 0, having an end loop, d, is clamped down by a thumb-screw, E, onto the disk b, to prevent the spindle with its spool from turning aftera rail length has been unwound.

The frame D is hinged to fram so as to turn up over the long table G after e spool and spindle have been removed. This enables the whole to be handled more conveniently.

g g are screws for setting or adjusting the former-plate n, and may be used with or without an intermediate washer.

The rail metal H is carried up from the spool over the end of table G and under the keeper or guide I; then over the chisel J; then between the die and punch L M. It is then carried over and under the formers or bars N, arranged alternately in two parallel rows on supports a, and, finally, between the punch and die L M. Now the punches are struck to make the end holes, pp, (shown in Fig. 3 of the drawings.) and the rail-sheet is forced down on the chisel to cut off the desired length of rail. After each rail is shaped, the holes punched, and the rail cut oil llolll the spindle-strip it is hung up on the rack 13, the first one upon the hooks It, the next one upon the first, the third one upon the second. and the fourth upon the third, thus forming a panel. The lower row of hooks, It, serves to hold the rails at a proper tension until they acquire the proper set, when the panel is removed from the rack-bars i Of course any desired number of rails may be used in a panel.

The metallic strip or wire rails are galvanized, and the panels are preferably placed on frames before shipping.

Having thus described all that is necessary to a full understanding of my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. The combination, with the spool and its frame, guide, and table, ofthe two parallel rows of formers N, arranged to alternate, as shown and described.

2. The combination, with the table, guide, and formers, of the punches and dies, arranged as and for the purpose set forth.

3. The combination, with the table, guide, punches, dies, and formers, of the chisel, arranged as and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM BILLINGS.
